Shisimona, that doctor seems to be strongly pushing personal his views on you. Very unprofessional behaviour. If she wants to do counselling, look for a service which offers unbiased advice and who will discuss the pros and cons of each option. Hopefully our Canadian posters can recommend somewhere.
You say that you believe that you're both capable of raising a child. Given the very unstable recent history you share with her, I hope you're not planning a 'happy family' scenario. As the relationship is rocky, odds are that the relationship won't go the distance. She needs to think long and hard about the high odds of ending up a single mother and whether or not she's up for it.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
